Floors
Above Ground

The number of floors above ground should include the ground floor level and be the number of main floors above ground, including any significant mezzanine floors and major mechanical plant floors. Mechanical mezzanines should not be included if they have a significantly smaller floor area than the major floors below. Similarly, mechanical penthouses or plant rooms protruding above the general roof area should not be counted. Note: CTBUH floor counts may differ from published accounts, as it is common in some regions of the world for certain floor levels not to be included (e.g., the level 4, 14, 24, etc. in Hong Kong).

Other Names

Other names the building has commonly been known as, including former names, common informal names, local names, etc.

Name of Complex

A complex is a group of buildings which are designed and built as pieces of a greater development.

Type

CTBUH collects data on two major types of tall structures: 'Buildings' and 'Telecommunications / Observation Towers.' A 'Building' is a structure where at least 50% of the height is occupied by usable floor area. A 'Telecommunications / Observation Tower' is a structure where less than 50% of the structure's height is occupied by usable floor area. Only 'Buildings' are eligible for the CTBUH 'Tallest Buildings' lists.

Country

The CTBUH follows the United Nations's definition of Country, and thus uses the lists and codes established by that organization.

City

The CTBUH follows the United Nations's definition of City, and thus uses the lists and codes established by that organization.

Address
Function

A single-function tall building is defined as one where 85% or more of its usable floor area is dedicated to a single usage. Thus a building with 90% office floor area would be said to be an "office" building, irrespective of other minor functions it may also contain.

A mixed-use tall building contains two or more functions (or uses), where each of the functions occupy a significant proportion of the tower's total space. Support areas such as car parks and mechanical plant space do not constitute mixed-use functions. Functions are denoted on CTBUH "Tallest Building" lists in descending order, e.g., "hotel/office" indicates hotel function above office function.

hotel / residential / office
Structural Material

Steel
Both the main vertical/lateral structural elements and the floor spanning systems are constructed from steel. Note that a building of steel construction with a floor system of concrete planks or concrete slab on top of steel beams is still considered a “steel” structure as the concrete elements are not acting as the primary structure.

Reinforced Concrete
Both the main vertical/lateral structural elements and the floor spanning systems are constructed from concrete which has been cast in place and utilizes steel reinforcement bars.

Precast Concrete
Both the main vertical/lateral structural elements and the floor spanning system are constructed from steel reinforced concrete which has been precast as individual components and assembled together on-site.

Mixed-Structure
Utilizes distinct systems (e.g. steel, concrete, timber), one on top of the other. For example, a steel/concrete indicates a steel structural system located on top of a concrete structural system, with the opposite true of concrete/steel.

Composite
A combination of materials (e.g. steel, concrete, timber) are used together in the main structural elements. Examples include buildings which utilize: steel columns with a floor system of reinforced concrete beams; a steel frame system with a concrete core; concrete-encased steel columns; concrete-filled steel tubes; etc. Where known, the CTBUH database breaks out the materials used in a composite building’s core, columns, and floor spanning separately.

About Suzhou Zhongnan Center

At 729 meters, the Suzhou Zhongnan Center is positioned to be the tallest building in China, and the third tallest in the world when it is completed in 2020. On a site to the west of Lake Jinji, close to the “pants-like” Gate to the East, the tower will dominate the skyline of Shanghai’s sister city of Suzhou. The development of this tower coincides with the rise of the city itself. With a growing population of more than 10 million, the city’s canals, gardens, and emerging technology and financial districts are transforming it into a world-class city that accommodates residents and tourists alike. The tower will incorporate hotel, residential, and office uses, some of which will be dedicated to SOHO (Small Office/Home Office) spaces, very small business environments that cater to firms of one to four people

The design of the tower was inspired by Jiangnan culture, referencing its pointed pagodas and local artesian wells. At the base, the podium lifts upward to resemble a flying lantern, establishing a public plaza at ground level. As one enters the tower and moves inward, the interior geometry alters to indicate a transition from public to private space. The isolated podium attaches to the tower via a translucent façade, lit by fritted glass along the exterior. Unlike other buildings designed at this height, the tower is four-sided and features a consistently smooth facade. The consistent appearance is only broken by the louver systems at mechanical floors.

The tower gently tapers as it rises, forming a pointed crown that caps the precipice. In addition to providing an aesthetically appealing terminus for the tower’s form, the crown also plays a critical role in the building’s structural performance. In a remarkable feat of engineering, it will contain both a 750-ton tuned mass damper (TMD) and a tuned sloshing damper (TSD). The tuned sloshing damper serves a double purpose as a container for emergency sprinkler water.
